AEC3 is a consulting company specialising in research, development and application of building information modelling BIM technologies. It has offices in UK and Germany, and works with clients (designers, construction companies, owners and operators) helping them to adopt and implement interoperable open BIM workflows.

AEC3 is a leading organisation for developing and using IT standards for the exchange and sharing of building information. AEC3 personnel provide leadership in the development of Industry Foundation Classes IFC, the open BIM standard how in process of becoming a formal ISO standard as ISO16739. AEC3 has also been instrumental in developing the neighbourhood standards Information Delivery Manual, IDM (ISO29481), and the Framework for BIM Guidelines (ISO12911). AEC3 works with and contributes to standardization organisations such as ISO, buildingSMART, British Standards and DIN.

AEC3 has been working in the area of data interoperability between the building and construction domain and the GIS / City model domain; the utilization of BIM for various evaluation and simulation tasks; the integration of the BIM tools of architects, engineers and operators with energy analysis tools; and the methods to transform the different data models using in BIM (IFC, gbXML) for the use in energy analysis tools and services. As part of the overall consultancy services that AEC3 provides for clients it also focuses on new ways of working, including the Integrated Project Delivery (IPD). The company has gathered experience through their work in numerous European projects including ISTforCE, ICCI, prodAEC, SWOP, InPro, STAND-INN and HESMOS.
